Specification of Letters Patent.

Patented 1 une 29, 1215.

To all whomc't may concern:

Be it known that I, ADELAIDE Lovnnenne, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Change- Makers, of which the following is a specification.

This invention relates to certain new and useful improvements in change makers, and the primary object of the inventionis to provide improved means for rendering the apparatus certain in its operation so as to not furnish an excess of small coins for one of a larger denomination, and to also prevent fraudulent operation of the machine or tampering therewith.

Further, the invention aims to generally simplify devices of this character, and to reduce the number of moving or operating parts, so as to thereby correspondingly reduceto a minimum the possibility of the parts becoming deranged or rendered inoperative.

Still further, the invention alms to provide improved shutter mechanism which automatically closes the coin slot when the apparatus has been emptied of coins used in the making of change.

Other and further objects will be later set forth and of themselves manifested in the course of the following specification.

In the drawings-eFigure 1 is a vertical sectional view of the invention. Fig. 2 1s a front elevation, partly broken away and in section. Fig. 3 is a section on the line 33 of Fig. 1. Fig. 1 is a top plan view with the cover removed, and Fig. 5 isa View similar to Fig. 1 with the parts 1n dliferent positions. I

The invention consists of a casing 1 having a coin receiving slot 2 which allows the coin to drop onto the inclined guide-way 1 and to enter the coin chute 9. The guideway 4: is formed with side ribs 5 spaced so as to just receive therebetween the com to be changed, which for purpose of example is assumed to be a nickel.

An opening 6 is formed in the bottom of the guideway A so as to allow a penny or a dime to drop therethrough wlthout operating the machine as shown in dotted lines at C in Fig. 1. Below the guideway 1 a chute 7 is disposed to receive small coins which'drop through the opening 6 and to convey such small coins to a cup 8 located exterior of the casing and accessible to a person operating the apparatus.

Coin chute 9 leads from the lower end of guideway A and discharges the nickel onto a plate 10 (Fig. 4:) which plate is supported by a light spring rod 11 and is located at the lower end of chute 9.

The pennies are stacked within the tubular holder 12 below which a slide 13 op erates, the slide having a penny receiving opening 14 which is of a depth to receive but five pennies when the opening registers with the lower end of the holder 12.

A latch 15 connected to the slide 13 normally holds the slide locked in out position by engagement with the spring rod 11 as shown in Fig. 5, the latch being held against operation or held locked by the spring 11.

A coiled spring 16 is connected to the slide 13 and to the casing and acts to pull the slide inwardly so as to receive a charge of five pennies. A lever 17 ispivoted to the casing at 18 and at its lower end bears against the slide 13 and at its upper end is engaged by a push rod 19 which projects without the casing so as to enable the slide to be moved to discharging position.

A shutter 20 which is weighted or overbalanced is pivoted to the casing in a position so as to close the coin receiving slot 2 when all of the pennies in the tubular holder 12 have been exhausted, the shutter being connected to a cord or cable 21 which latter in turn is connected to a weight 22 that slides in the holder 12 so that the weight will, upon exhaust of all of the pennies, pull the shutter to a position where the same closes the coin receiving slot 2.

In operation, the parts normally occupy the position shown in Fig. 5 in which the pennies in the holder 12 rest upon a blank portion of the slide 13, the latter being held in the position shown in Fig. 5 by means of the latch 15 and the wire spring 11 and against the tension of the spring 16 which tends to pull the slide inwardly. When a nickel is inserted in the slot 2 it drops on guideway 4c and passing down the latter enters chute 9 and gravitating through the chute strikes plate 10, effecting release of the latch 15 by moving spring rod 11 out of the path of the latch, which now allows the spring 16 to contract and to consequently pull the slide 13 inwardly into position 110 where the opening 14 receives five pennies. The operator now presses inwardly on the rod 19, which through the lever 17 moves the slide and therewith the five pennies outwardly to a position where same drop into the chute 23 and are discharged into the cup 8. The act of the rod 19 and lever 17 in moving the slide outwardly effects resetting of the parts in locked position ready for further operation of the machine.

It will thus be seen from the above that the slide is normally in out position in which position the slide cannot be tampered with, even by operating push rod 19, nor can pennies enter the receiver 14 of the slide, but as soon as a nickel engages the plate 10 and releases the latch 15, the spring 16 acts to draw the slide inwardly into such position as causes the receiver14 of the slide to register with the holder 12 and to allow five pennies from the holder to enter the receiving opening 14 (Fig. 1). Then when the operator moves the slide outwardly the pennies are discharged and the parts automatically reset, or relocked ready for further operation of the machine. By requiring that the slide must move in before the same can be charged with pennies it will be seen that fraudulent operation of the machine by persons tampering therewith is prevented, smce the slide can move inwardly only when a. nickel is deposited in the machine. The nickel drops into the compartment 24 shown more clearly in Fig. 2.

For the purpose of limiting the inward movement of the slide so as to assure the receiver opening 14 registering with the holder 12, a stop 25 (Figs. 4 and 5) is employed.

Obviously the machine can be employed for coins other than nickels, the present example of use with nickels being merely for purpose of illustration.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a change maker, a casing having a coin holder, a slide beneath the holder having a receiver opening of a depth to receive only the proper number of coins, a spring to move the slide inwardly to cause the receiver opening to be disposed in register with the holder, a latch on the slide, a spring rod engaged with the latch to hold same and the slide against the tension of the spring, a plate on the rod operable by a descending coin to move the rod out of engagement with the latch to thereby allow the spring to move the slide inwardly to cause the receiver opening to register with I the holder and to receive a charge of pennies, a lever pivoted to the casing and engaged with the slide to move the latter outwardly and a push rod to actuate the lever.
